After reading this review you might wonder why you would need to buy a device like this. If you're looking for a NAS to quickly share files, there are other products that are better in terms of pure speed. The performance with the NAS Performance Tester is good, but the 5big Office+ didn't do as well with the more practically-oriented Intel NAS Performance Toolkit. Synology or QNAP have products that are better suited in that case. But if you need a good back-up solution for a small business with an Active Directory and up to 25 PCs, then this is a good solution. The fact that it also looks good, is an added bonus.
